Small Bugfix Update

Currently working away on the full game, but caught a few issues I wanted to patch in the demo:

• Fixed a bug which was setting some field prices significantly higher than intended (Radishes, Cucumbers, Corn, Tomatoes)

• Raised priority of Business Collection trucks so they are more likely to get access to products when competing.

• Fixed some issues with distribution/pickup of plot contents while they are upgrading.

• Tweaked some plot window toggle button behavior to more clearly display their current state.

• Fixed issue where deleting a plot while one of its trucks was making a pickup causing backups in the plot being picked up from.

• Attempted fix for some possible issues from phantom/ghost mouse clicks.

• Tweaks to some keyboard navigation logic.

Thanks to everyone who's reported these!
